Application of Ruscheweyh Derivative to Univalent Functions with Negative CoefficientsKeywords: Ruscheweyh derivative , distortion theorem , coefficient bounds. Abstract: The systematic investigation of a new class of analytic functions, which is defined in terms of Ruscheweyh derivative, is presented. Apart from coefficient bounds, results like distortion property, closure property and radius of starlikeness of this class of functions is obtained.
